UXPin

UXPin is a code-based design and prototyping platform that bridges the gap between design and development by allowing teams to build interactive prototypes with production-ready components. Unlike traditional image-based design tools, UXPin renders designs using real code, enabling pixel-perfect consistency between what designers create and what developers ship.

Founded in 2010 and used by over 500,000 designers and developers worldwide, UXPin has established itself as a leading choice for enterprise design teams at companies including PayPal, Microsoft, Xerox, and Kimberly-Clark. The platform processes millions of prototypes and supports teams across 190+ countries.

UXPin's standout capability is Merge technology, which allows designers to import and use live React, Storybook, Angular, Vue, and npm components directly on the design canvas. This means prototypes behave exactly like the final product, complete with real data, states, and interactions. Merge 4.0, released in 2025, introduced enhanced component syncing, improved performance, and deeper Git integration for seamless design-to-development handoffs.

The platform includes advanced prototyping features that go well beyond simple click-through mockups. Designers can add conditional logic, variables, expressions, and multi-state interactions without writing code. Form elements work with real data validation, and prototypes can connect to external APIs for dynamic content. These capabilities make UXPin prototypes suitable for usability testing that closely mirrors actual product behavior.

UXPin's built-in design system management allows organizations to create, maintain, and distribute a single source of truth for their design language. Teams can build pattern libraries with documented components, enforce brand consistency through shared styles, and track design system adoption across projects. The design system editor supports versioning, access controls, and automated style guides.

In 2025-2026, UXPin introduced AI-powered design assistance features, including AI-generated layouts, content suggestions, and automated component recommendations based on design patterns. These features help designers move faster from concept to high-fidelity prototype while maintaining design system compliance.

Collaboration features include real-time co-editing, commenting with threaded discussions, design reviews with approval workflows, and stakeholder preview links. UXPin integrates with development workflows through Jira, Slack, Microsoft Teams, and supports design token export for seamless handoff. The platform also offers built-in accessibility checking tools to help teams meet WCAG compliance standards.

UXPin provides a browser-based editor requiring no software installation, with projects stored in the cloud for access from any device. The platform supports both free-form design and component-driven workflows, making it adaptable to teams at various stages of design system maturity.
